A circuit breaker is an automatic electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. It is commonly used in homes and businesses to provide overload protection from devices such as stoves and dishwashers. The W28-X1029-5 circuit breaker is a single-pole circuit breaker with a thermal and thermal-magnetic trip action and is suitable for applications with a maximum rated current of up to 20 amps.

The W28-X1029-5 circuit breaker is especially designed for installations in which the circuit breaker will be exposed to high temperatures or if the load connected to it is prone to abrupt load changes. It is designed to be reliable and to provide reliable circuit protection in a wide range of applications and has a rated voltage of 120 volts.

Applications

The W28-X1029-5 circuit breaker is designed for use in a variety of residential and commercial applications including lighting, air conditioning, heating, and cooking systems. It can also be used to protect motors, pumps, elevators, and other systems and systems components with similar ratings. This type of circuit breaker is often used in installations where it is subject to thermal or thermal-magnetic trip action. In such instances, the W28-X1029-5 helps protect the circuit from potential damage caused by an overload.

The W28-X1029-5 circuit breaker is suitable for use in areas with automatic control systems, such as air conditioning systems or electrical distribution systems, as well as for industrial use for motor control and electric motor drives. It is also a popular choice for use in industrial applications where it may be subject to additional thermal-magnetic trip action.

Working Principle

The W28-X1029-5 circuit breaker works by detecting an over-current condition and opening the circuit to prevent further damage to the system. It is designed with two trips; a thermal trip and a thermal-magnetic trip. The thermal trip works on the principle of a bimetallic strip which is heated by the current in the circuit and bends or breaks when the current reaches a certain level. The thermal-magnetic trip works on the principle of current moving through a magnetic field, which causes the magnetic field to deflect and open the circuit.

The W28-X1029-5 circuit breaker also features a built-in ground fault circuit interrupter (GFCI) which detects and opens the circuit when it detects an electrical fault. This feature helps to provide an extra layer of protection against electric shock. It works in the same way as the GFCI outlet, by detecting small currents in the circuit and automatically cutting off the power to prevent further damage.

The W28-X1029-5 circuit breaker is designed to provide reliable circuit protection and is easy to install and use. It is a great choice for use in a variety of residential and commercial applications where reliable circuit protection is needed. It offers both thermal and thermal-magnetic trip action, along with a GFCI, providing additional protection against electric shock.
